CONTAINER.

Application filed June 29, 1926. Serial No. 119,459.

This invention relates to improvements in containers, and particularly containers of the type used to contain ingredients which it is desired to dispense interi'nittently, particularly such materials as pastes, creams, plastics and the like, and the objects of the invention are to provide a simple, inexpensive form of extruding device operated by reciprocable motion which may bemanufactured at low cost and so be available for use in containers or packageswhich are not to be filled, and consists essentially ofthe improved construction hereinafter described in detail in the accompanying specification and drawings.

In the drawings, in which like characters of reference indicate corresponding parts in all figures:

Figure 1 is a sectional elevation of an embodiment of my invention;

Figure 2 is a cross section on line 2-2 of Figure 1;

Figure 3 is a perspective view showing the end of the spring-operating member;

Figure 1 is a sectional elevation through an alternative form of the invention.

Referring to the drawings, A indicates a container of any convenient material selected with reference to the character of the material to be contained, and may, for instance, be thin sheet metal, celluloid, porcelain, glass, vulcanite or the like. In the form illustrated, the container is cylindrical and, in Figures 1 and 2, formed with a rotatable reciprocable cap B fittingthe end of the container. In Figure 4 the top 10 is partly covered over and a reciprocable nozzle B is provided. The material is designed to be extruded through a suitable orifice the out-- let to which is controlled by a reciprocable member, which member also operates the extruding means. In Figure 1 the cap 13 constitutes the reciprocable member, and the orifice 11, through which the material is extruded, is formed in a container, said orifice being designed, when the cap is in a given position, to register with a passageway or opening 12 in the cap. The extruding means or member illustrated. comprises a followeror pressure applying member C conveniently constructed of light, resilient material such as cork, and fitting closely to the inner surface of the container A, which is preferably cylindrical. This member C is operated from the reciprocable member by a connecting or propelling member D convenlently 1n the form of a spiral spring whlch extends spirally through the member C after the manner of a corkscrew, being locked therein by a transverse pin 13 which extends be tween two turns of the spiral.

In order toform an intermittent or ratchet connection between the member B and the member D, an enlarged turn 14 is formed on the spring D and provided with a turning point 15 designed to engage an annular surface 16 provided on thecap B, the member D extending through anaperture 17 in the cap B andthe annular surface 16 forming the bottom of arecess 18 of the cap, the top of which may be conveniently closed with a cap 19. The member D is convcniently formed of a light somewhat extending spiral spring and is preferably arranged under slight tension so that its tension will hold the cap on the container and tend to draw the member C towards the cap. The lower part of the spring extends adjacent to the bottom of the container. The cap B is preferably formed of material which the pointed end 15 of the spring may penetrate slightly as, for instance, wood, so that the pointed end and the surface 16 may constitute a ratchet connection between th spring D and the cap B.

In operating the form of the invention shown in Figure 1, the arrangementwill be such that when the material is not to be used, the aperture 12 will be out of registration with the orifice 11 and may be turned for instance one-quarter or one-half a revolution away from the same. When it is desired to use the material the cap willbe turned to bring ,the openings 11 and 12 into registration. Thus turning movementwill, through the ratchet connection, turn the member D which will turn and raise the member 0 towards the cap B, thereby causing the material in the container to be 6X truded. On the return movement the point 15 will slip over the surface 16 and no material will be extruded.

In the form shown in Figure 4, the turning end 20 engages an annular orratchet surface 21 or a reciprocable nozzle which fits in a socket 22 on the top of the container.

As many changes could be made in the above construction, and many apparently ter contained in the accompanying specification and drawings, shall beinterpreted as illustrative and not in a limiting sense. What I clann as my invent-1011 is:

1. In combination. a container having an orifice through which material may be extruded, an extruding member, an operating member on the container, a. spiral spring forming a connection between the operating and the extruding member and. having the end of the spring forming a releasable connection with-the operatingmember.

2;..In combination, a container having an orifice through which material may be extruded, an extruding member, a reciprocable member on the container, a spiral spring forming a connection between the reciprocable and the extruding member and: having theend of the spring forming a releasable connection with the reciprocable member, said reciprocable member being formed with an annular engaging surface with which the spring engages. 1

3. In combination, a container having an orifice through which material may be extruded, an extruding member, a reciprorable member having an annular surface, a spiral spring forming an operable connection between the reclprocable and the extruding membershaving a turned end engaging the annular surfac i 4. In combination, a container, av reciprocable cap, a follower in the container and a in one direction only will impart movement to the spring to thereby actuate the follower member.

In witness whereof I have hereunto set my hand.

WILLIAM HENRY GREGORY GEAKE.
